3 Claims. (Cl. 312-39) My present invention relates to dispensers forrolled sheet material and particularly to dispensers for cotton in sheetform.

Heretofore there have been many rolled sheet dispensers, but usuallysuch dispensers are made with spring activated feed rollers and numerousparts which are permanent parts of the dispenser case. Suchconstructions are likely to get out of order and require too much laborand time to manufacture, so that the initial expense of the dispenser ishigher than most people will pay. Also, such prior art dispensers whenthey become out of order, such as the spring or the feed mechanismbecoming broken are then usually worthless and. not repairable by theaverage user.

One object of my invention is to eliminate spring activated feed rollersand other feed arrangements, such as usually get out of order and cannotbe repaired.

Another object of my invention is to provide a compact and economicalwall mounted dispenser comprising a unitary casing open at the top andhaving a plurality of detachable independently manufactured parts forquick assembly as a part of the casing to form the completed dispenseror for ready interchanging.

With the above and other objects in view the device consists of theparts, arrangement, and

combinations thereof described in the following description andillustrated in the accompanying drawings, wherein:

Fig. 1 is an isometric view of my invention mounted on a wall or thelike ready for use as a dispenser.

Fig. 2 is a transverse cross section view taken on the section line 2-2of Fig. 1.

Fig. 3 is a longitudinal cross section view taken on the section line 33of Fig. 3.

Fig. 4 is a perspective view of a roll holder or tray such as isdetach-ably mounted in the dispenser casing shown in the precedingfigure.

Referring in detail to the drawings by reference characters for theseveral parts of my invention and first with special reference to Figs.1 and 2, there is illustrated a rectangular box or casing l0 formed witha bottom wall II, front and rear walls I2 and I3 and end walls I4 andI5. The top of the box I0 is open, but it is closable by a closure l6pivoted to the top edge of the rear wall 13 by a multipintle hinge IT.The closure [6 is formed with a depending skirt I8, which overlaps thetop edge surface of the box walls. Also to hold the closure in closedposition the same is provided with a yieldably resilient latching tonguel9, which frictionally engages the side of the front wall l2.

The front wall I2 is formed with an elongated longitudinal guide slot 20for a, shaft 2| carrying a cutter blade or knife 22. This shaft isthreaded into a threaded socket in the body of the knife, which shaft isslidable with the knife along the slot within the box 10. The shaft 2|extends through this slot and supports a handle 23. Vertical movement tocompensate for the thickness of the sheet to be cut is provided byvertical slot 24. Slot 20 is superimposed above a dispenser slot 25 inthe wall [2. The lower edge of the wall I2 at slot 25 is bent over fromthe slot opening 25 to form a lip or rest surface 28 with a curved downedge extending exteriorly of the wall. Rearward. of the slot 25 andextending interiorly of wall I2 is an elongated anvil surface 21, seeFig. 2, with a knife edge receiving groove 28 along and within which thecutting edge travels for the purpose of transversely cutting a sectionof material, such as sheet cotton 29 from the roll of cotton 30 or thelike after it has been pulled from the box through dispensing slot 25.

The dispensing mechanism within the box H1 comprises a plurality ofinterchangeable parts, the box having each end wall l4 and I5 formedwith a pair of superimposed oppositely aligned openings to receive theshaft ends of the feed rollers 31 and 32 spaced rearwardly on each sideof the edge of the anvil plate 21.

The roller 32 is a drive roller and may be made slightly oval in crosssection to facilitate the dispensing action of the rollers on the web ofthe strip as it is thus unwound from the roll 30. The power to theroller 32 may be supplied by a. handle or crank 34, which has a socketadapted to thread into the extended end of the shaft end of roller 32.The web pays out from the top of the roll 30, which is supported in aroll conforming yieldably resilient trough 33, under an idler guideroller 35. The roller 35 has extended shaft ends extending throughoppositely aligned openings in the box end walls l4 and 15,respectively.

The end wall [5 of box In is formed from the top rim thereof with a slot36, see Fig. 2. The slot 36 terminates a short distance from the top rimint-o a curved bearing surface upon which rests the stud shaft 31 formedfrom the yieldwhen supported in the box Ill each ear presses intofrictional contact with the adjacent inner surface of its respectiveside wall, namely 14 and I5. Thus the ears serve as friction brake meansto hold the trough in position. The side wall [4 is formed with anopening oppositely aligned with respect to the curved bearing surface atthe terminal end of slot 36 to receive the stub shaft 40, therebycompleting the support of the trough 33. The trough is formed along itsforward longitudinal edge with a yieldable resilient curved tongue 4|,see Fig. 4, and along its rear longitudinal edge with a downwardlycurved bead 42, thereby forming a smooth convex surface over whichtravels the web of strip cotton or the like as it is pulled forward bythe dispense ing rollers 3| and 32.

The roll of strip cotton to be dispensed is clamped or gripped by theresilient tongue 4 I, as this tongue due to the inherent resiliency ofthe trough material is formed to yieldably bias upward toward the rearwall of the trough 33. Thus when rolls of various sizes are in thetrough the tongue 4! serves to hold them in position, so that eventhough the pull on the web 29 should become excessive and cause thetrough to rock or rotate in the direction of pull, the roll will notdrop from the trough. Normally the friction brake, that is, the ears 38and 39 will hold the trough fixed.

The fact that the trough is rotatable upon excessive pull caused byunexpected binding or jamming at the dispensing slot 25 is a verybeneficial feature, as with this rotatable floating arrangement thetrough will automatically release any such binding or jamming.

The rear wall of the box 19 is formed with keyhole slots 43 and M toprovide for mounting the device upon a wall or other vertical surfaceand when it is desired to load the device it may be detached from thewall, if desired.

Operation The use of the device is probably apparent from the foregoingdescription. However, assuming the device is mounted on wall, briefiythesteps of operation are to first raise the box cover ii) to load thedispenser by positioning the novel trough 33' with a roll to bedispensed therefrom gripped therein by trough M in its friction brakedsupported position between end walls l4 and I5, next the web of materialis manually unrolled from the top of the roll over the convex roundedsurface of bead t2 and turned around the underside of guide roll andinto the bight of the dispenser rollers 3| and 32, through the slot 25trough being formed. at each end with outwardly During each dispensingmovement of the web 29 by the feed rollers, the trough 33 will normallybe held against forward rocking by the frictional resistance between thebrake cars 38 and 39 and their respective side walls, but if the feedshould jam ahead of the rollers 3! and 32 the trough will turn, therebyrelieving any excessive tension on the web and thus permit the web tofeed forward easily until the jammed condition is corrected.
